VTo ALL WHOM 1T MAY ooNoEsN: i

Be it known that I, JQHNSOUTHER, of the city of Boston, county ofSuffolk, and State of Massachusetts', have invented a new and usefulimprovement, a machine, or a combination of machinery, for the purposeof more promptly giving n. fire-alarm, and extinguishing a lire. I dohereby declare that the folloiving description, specification, andaccompanying drawings, is a true description of the construction andoperation vof the same.

The object of my invention is, when a. building or vessel is on fire, touse the fire as the agent to give the alarm by a steamor gas-whistle,and also put out the fire byA steam, gas, Aor water, making itself-operating.

Drawing A, Figure 1, is a side elevation. l

Letter A, on drawing, represents a. steam or gas-pipe broken oft', whichpipe leads to or from the steamboiler; B s a. steam-whistle ;V C is a.cock o r valve; D is aline or any combustible attachment leading acrossa room'or vessel, and secured there, sc asto raise the weight E olf thelever F, by passing over pulley G.

When `the fire comes in contact with `this attachment tosever it, itdrops weight E snfll lever F, and opens valve C, and lets steam in theroom, or'gas under pressure, coming in Contact of whistle, giving analarm, and putting out the re lby the steam or acid gas. Water may belet on the re by the same motion.

H H is a gasgor steam-pipe brokeniofi, which pipe leads across the roomor vessel, for the purpose ofletting on steam in different places in thebuilding or vessel, by the heat of .the re melting a metallic fusibleplug, I, which melts at a low degree of heat, and, when melted, letssteam through the apartment it covers; also by igniting a combustiblefuse in opening of pipe marked J, and by the expansion of the pipe bythe heat of the fire, thereby forcing valve-stem K against block L,opening the ,valve inwardly, letting out steam, all for the purposeabovenamed. i

1L A selioperating lire-alarm and extinguisher, consisting ofthe pipes Aand H, vfhistle B, valve C, lever F, and weight E, o'r theirequivalents, all constructed and arranged to operate substantially asherein described.

2. The pipes A and H, fusible plugs I and J, anll valve-stem K,constructed and arranged to operate substantially as herein describedand for the purpose set forth.
